Port City of Khorramshahr on the Shatt al-Arab River, Iran30.4N 48.1E
The Shatt al-Arab or Arvand River is a river in Southwest Asia of some 200 kilometres (120 mi) in length. It is formed by the confluence of the Euphrates and the Tigris in the town of al-Qurnah in the Basra Governorate of southern Iraq.
The southern end of the river constitutes the border between Iraq and Iran down to the mouth of the river as it discharges into the Persian Gulf.
It varies in width from about 232 metres (760 ft) at Basra to 800 metres (2,600 ft) at its mouth. The Karun River, a tributary which joins the waterway from the Iranian side, deposits large amounts of silt into the river; this necessitates continuous dredging to keep it navigable.
Visible near the center of the image is Khorramshahr, a port city in Khūzestān Province in southwestern Iran. It is approximately 10 kilometres (6.2 mi) north of Abadan. The city extends to the right bank of the Shatt al-Arab waterway near its confluence with the Karun River.
